Definitions

  • the invention relates to a tire building machine for the preparation of pneumatic tire blanks with a building drum for receiving tire layers and a pressure roller cooperating with it.
  • Tire building machines for diagonal as well as for belt tires as well as for two- or single-stage tire building are generally provided with various ply feeders and other devices which serve to feed and treat the individual blank components.
  • a separate, specially designed treatment device is provided for each of these components, for example several layer rollers, pinch rollers, pressure rollers, splice rollers and the like.
  • Resilient pressure rollers are made of foam and do not allow any pressure regulation that can be adjusted or controlled via the blank width and the blank circumference.
  • the disks are designed identically to one another, that each disk comprises an inner part and an outer ring surrounding it rotatably via a ball bearing, and that the inner part has a substantially rectangular recess, with the side faces of which it is on the side faces the axis, which is rectangular in cross section, slides radially to the building drum and its length is one stroke longer than the corresponding length of the cross section of the axis.
  • This configuration is very simple and inexpensive, low maintenance and low wear.
  • separate or suitably connected pressure generating devices can be accommodated for each disk in order to control the pressing force of the disks in the direction of the building drum.
  • a head and foot displacement each formed a lifting hose which extends over the length of the pressure roller and can be acted upon by a pressure medium is arranged.
  • This can be made from an elastic or inextensible but foldable pressure-medium-tight inner wall and a tissue envelope surrounding it to reduce wear. Different areas of the head and foot displacement can be acted upon differently and thus generate different pressure forces of the individual disks and certain disk groups over time or over the length of the pressure roller.
  • the pressure of the pressure medium in the lifting hoses can be regulated. Stroke differentiation can also be achieved by adjustable throttle installations in the lifting hose.
  • the discs are expediently made of a material with good sliding properties and non-stick properties to the tire components, for example suitable plastic, and are optionally additionally subjected to a sandblasting treatment on the surfaces facing the rubber material.
  • a movable holder for a pressure roller of a tire building machine which is otherwise not shown, there is an axis 1 with an approximately square cross section that cannot be rotated.
  • the pressure roller can be adjusted radially to the building drum of the tire building machine by means of the holder or its drive.
  • a large number of disks 2, which are the same as one another, are also arranged such that they cannot be rotated, but can be displaced radially to the building drum, over their usable working length.
  • Each disc has an inner part 3 and an outer ring 5 surrounding it via a ball bearing 4.
  • the inner part 3 is provided with an essentially rectangular recess, with the side surfaces 6 of which it slides on the side surfaces 7 of the axis 1.
  • a lifting hose 10, 11 which extends over the length of the pressure roller and can be acted upon by compressed air is drawn into the head displacement space 8, which is formed between the head and foot surface of the recess on the one hand, and the corresponding surfaces of the axis 1 and faces the construction drum and faces the construction drum .
  • Air connections 12 are attached to the ends of the lifting hoses 10, 11.
  • an interchangeable clamping piece 13 is used, by means of which the lifting tube is compressed in the head displacement 8, so that the pressure of the disks 2 assigned to the central part on the building drum is increased while the pressure is not changed.
  • the disks 2 are made of material which provides particularly slidable surfaces and which also has good rolling properties in the ball bearing 4.
